Rev Limit 3Step
The 3Step Rev Limiter is a simplistic traction control system that is commonly used in race
series that do not permit wheel speed sensors. Instead this system uses the transmission's
vehicle speed sensor along with the crank sensor(engine speed) to limit the amount of tire slip.
There are two tables (3StepFuelCut and 3StepSparkCut) that are associated with the following
channels.
3 Step Fuel Cut Enable:
Enable or disables the fuel cut 3 step feature.
3 Step Spark Cut Enable:
Enable or disables the spark cut 3 step feature.
The 3Step Target tables shown above are used in conjunction with the setup wizard options.
